Hm, I'm a bit confused. So we know that the Keyman in the last chapter smashed Alex's right hand, but when Alex meets Pete and Flor after being let go, we can see that his right hand appears fine. However, at the end of the chapter, we see that Alex has indeed gotten a hook to replace his right hand. Not sure what's going on, but I guess it makes for a nice reveal of the hook (although we did see it earlier in some cover art at the beginning of volume 6).
